SPECIFICATION forming part of Letters Patent N 0. 674,789, dated May 21, 1901.

Application filed September 29, 1900. Serial No. 31,562. (No model.)

To all whom it may concern-.-

Be it known that 1, WILLIAM JAMES PERRY MOORE, engineer, a citizen of the United States of America, residing at 7 Sloane street, London, IV., in the county of Middlesex, England, have invented certain new and useful Improvements in Connection with Pumps, (for which I have made application for Letters Patent in Great Britain, No. 4,302, dated March 6, 1900,) of which the following is a specification.

This invention relates to improvements in connection with pumps and the valve-chambers connected with the same, the object being to provide for a method of constructing and arranging the working barrels and the valve-casings which will obviate the disconnection of any part of the valve-chamber when the working barrel 0r water-cylinder is to be renewed or repaired. I am also enabled to provide a convenient arrangement of valves which will facilitate their examination and renewal, with a minimum amount of interference or disconnection of jointed surfaces.

In the accompanying sheets of explanatory drawings, Figure 1 is a sectional elevation of a pump having my improvements thereon, taken on a line X X on Fig. 4 in direction of arrow 1. Fig. 2 is a side elevation, and Fig. 3 is a front elevation, of the same. Fig. 4 is a plan of the pumps, showing the valve-covers in position. Fig. 5 is a sectional plan of the valve and water chambers, taken through Y Y on Fig. 1. Fig. 6 is a sectional plan of the valve and water chambers, taken on Z Z on Fig. 1. Fig. 7 is a sectional view on line 7 7 of Fig. 3.

In carrying my invention into effect when providing for a vertical type of pump I form my water-cylinders a in such a manner that they can be suspended from or independently attached to the casing or chamber 1), in which the valves are arranged. I may make the inlet connection to the lower end of the water-cylinder CL by means of an independent pipe, or I may provide for the passage to the end by means of a port or cored passage 0, cast in one with the pump-cylinder or water vessel 0,. The upper end of the water vessels I make to bolt or connect onto the valve chamber or casing 13, the valves of which are arranged concentrically about the pumpchamber, as shown in Figs. 4: 5, and 6.

In the duplex form of pump shown in the drawings the action of each pump is similar, and the parts of each pump are similarly let.- tered. Therefore a description of one will suffice for the other also.

The action of one pump is as follows: As indicated by the arrows in Fig. 1, water enters on the downstroke of the plunger (1 onto the top thereof through c e and on the up stroke is delivered from the top of the plunger through a valve g into a common deliveryf. At the same time on the upstroke water enters below the plunger up through the valves 6 e and down the passage 0 and on the downstroke is delivered from below the plunger back through the passage 0, past a valve g, into the common deliveryf.

I arrange my pumps in pairs, as shown in the accompanying drawings, to suit the wellcommon outlet or rising main passage f, as

shown in Figs. 1 and 6. I connect the rising main branch h to either side of the common passage f, placing a blank flange 7.", on the side not in use. The suction connection we I make to the common passage '11, as shown in Figs. 1 and 5.

I employ any ordinary type of valve in connection with my improved valve-casing and chambers, and I arrange covers lover each independent valve or seri'es of valves, so that one valve removal or series of valves being removed does not disturb another valve or series.

I modify the form of my valve-casing and the arrangement for securing the pump-barrels to suit the size, type, and purpose of the pump which is to be constructed. I may, for

pumps.

having a common suction-passage therein extending about the said chamber, suctionvalves for each barrel supplied from the said common suction-passage, discharge-valves in the valve-chamber for each barrel, and a com mon delivery passage for both barrels arranged centrally of the valve-casing, substantially as described.

In Witness whereof I have hereunto set my 20 hand in presence of two Witnesses.

WM. JAMES PERRY MOORE.
